IMPROVEMENT IN DlSTILLING HYDROCARBON OlLIS.

Spccilicalion forming part of' Letters Patent No. 11,137, datml Selm-mbit (i, lr'l.

.To all whoml z5 may concern,.-

Be it known that I, WILLIAM ARCHER, of the city, county, and State of New York, have invented a New Mode of Distilling Hydrocarbon Oils; and I do hereby declare that the .following is afull and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.4

The process of distilling hydrocarbon oilsWheretofore has vbeen by applying heat to the'bottom of the containing vessel or reservoir,'thereby evapofating, themand-separating the product-by what is known in chemistry as fractional distillation. In the' employment of such a method there .have 'arisen very many inconveniences, delay, and much Waste, and the design of my method of distillation is to obviate these objections. Hydrocarbon oils before distillationv contain many voiatileand-highlyi niiammable'and explosive substances, whichV may be .thrown off at different temperatures, and which are nec essary to be separated in order to produce a safe, valuable, and uniform article.

The .nature of my invention consists in a method by which snperheated steam or. hot air is applied to the continuous and fractional distillation of hydrocarbon oils in such a manner that each grade or product shall be evolved and deposited in a separate apparatus.

To enable others skilled in the art to make and use my invention, I will proceed vto describe its construction and operation.

The drawing exhibited is a cross-section of my invention.

c is a metallic still vessel or base, cylindrical in form,` put together in sections orcast complete, and as large as is most desirable.

When made in sections, the joints k k k k are close sealed with fusible metal. b is a leading-pipe connected with the steam4 or hot air apparatus and ruiming down into the lower chamber of the vessel. This tube is provided at the lower end and passes into an inverted metallic saucer ordetlectoxg` c, the diameter of which is slightly less than the greatest diameter of the still-vessel. i e is also a metallic disk, conforming to the deilector c in shape, diameter, and size, and is secured within from two to three inches of the deiiector by a step, f, in the center ofthe door of the vessel. d is a fecding'tubc, which may be either straight or spiral, the lower end of which opens upon the lower disk, e, while the up -per'end passes through the steam or hot air .tube b, in manner as shown; L

, h is a'removable cover, which, when the apparatus is jin operation, is sealed bya joint and fusible metal packing at k.

' is the .exhaust-pipe, which connects with any ordinary condensing apparatus.

th is a thermometer inserted in the exhausttube for the purpose of determining the tempera-ture of the distillingvapor.

l When I wish to operate my invention, l admit a continuous volume of superheated seam or hot air through the tube b uponthe 1 fwer disk, c, until the desired temperature is indicated by the thermometer. Vhen the necessary temperature is raised, I admit a stream ofv oil through the tube d, which is received upon the disk-e and flows in a thin liieet'othhntoward itsouter'edge. Ally the volatile matter the boiling-point of which is not higher than the specific heat' applied will mingle and rise with the steam or hot air applied and pass off through the exhaustpipe into the condenser, while the oils whose boiling-point is higher than the specific heat applied will drop from the outer edge of' the disk c to the door of the distilling-vessel,

l and will be discharged vthrough the tube g,

vand therefrom pass into the feedingtube d of the succeeding apparatus, in which the heat will be raised to the requireddegree necessaryto volatilize the next heavier product, and so on till the various specic products are all se `rated.

Having thus fully described the nature and operation of my invention, what I claim herein as new, and desire to secure by Letters Patent, 1s 1. The manner heieindescribed otcontinuously and iractioually distilliug andV separating the various parts of hydrocarbonoils by the application of superheated steam or heated air, substantiallyin the manner doscribed.

2. Thev combination of the heating-tuhe b. with the deecting and receiving disks c and e, with the spiral or straightieeding-tubc d, in the manner and for the purposes as def scribed.
